After dealing with TWO utterly unreliable Accu-chek Aviva meters–where from box to box the readings could vary by 50 mg/dl I switched to Ultra and I’ve been happy ever since.
I have a regular Ultra in my purse and an Ultra 2 upstairs where I work. They use the same strips so I can put a couple in my purse when I need them. They usually agree with each other and with themselves on two fast tests in a row.
Years ago I had a wonderful Accu-chek Advantage, which always matched the lab, but when I got a new one it wasn’t the same meter and the accuracy wasn’t there any more. Plus the runaround I got from customer service when I was getting crazy readings from the Aviva–and had just started insulin was not to be believed. They had one goal and one goal only–to keep from getting sued and it really showed in how they treated me when I reported my problem.
